Description

調光システムDimming system
　本発明は、電圧を印加することで光の透過率を変化させる調光システムに関する。 The present invention relates to a light control system that changes light transmittance by applying a voltage.
　近年、電圧を印加することによりガラスに設けた光の透過率を調整可能な、例えばスマートウィンドウと称される、調光機能を有する調光窓が実用化されている。 In recent years, a dimming window having a dimming function, for example, called a smart window, in which the transmittance of light provided on glass can be adjusted by applying a voltage has been put into practical use.
　このような調光窓は、窓の光学特性を可変することで、遮光や減光、遮熱等が可能であり、例えば建物や乗り物等における冷暖房負荷等を大幅に低減できることから、省エネルギー対策への取り組みの一環として注目を集めている。 Such dimming windows can be shielded, dimmed, or shielded by changing the optical characteristics of the window.For example, the cooling and heating load on buildings and vehicles can be greatly reduced, making it an energy-saving measure. As part of their efforts, it is attracting attention.
　一方、調光手段として表示装置を利用することで、調光窓を表示に利用する技術も知られている（例えば特許文献１等、参照）。 On the other hand, a technique of using a dimming window for display by using a display device as dimming means is also known (see, for example, Patent Document 1).
国際公開第２０１４／１７５１９０号パンフレット（２０１４年１０月３０日国際公開）International Publication No. 2014/175190 Pamphlet (October 30, 2014 international publication)
　このような調光窓を駆動するためには、少なくとも電源部と制御部とが必要となる。 In order to drive such a light control window, at least a power supply unit and a control unit are required.
　特許文献１には、複層ガラスに表示装置を設ける場合に、表示装置に電源供給や画像信号を供給するためのケーブルの視認による外観的な見栄えの低下や断線を防止するために、複層ガラスのスペーサにケーブル挿通路を設けることが開示されている。 In Patent Document 1, when a display device is provided on a multi-layer glass, in order to prevent deterioration in appearance and disconnection due to visual recognition of a cable for supplying power to the display device and supplying an image signal, the multi-layer glass is used. It is disclosed that a cable insertion path is provided in a glass spacer.
　しかしながら、特許文献１は、上記表示装置の電源部や制御部の配置については、特に言及していない。また、特許文献１は、電源や信号の入力が本体と一体化し、取り外しを前提としない、車両等の固定窓に上記表示装置を設けるものであり、例えば框（サッシ）のように、建物とは独立して交換が可能な部材に対する電源部や制御部等の配置については、何ら言及していない。 However, Patent Document 1 does not particularly mention the arrangement of the power supply unit and the control unit of the display device. Further, Patent Document 1 is provided with the display device in a fixed window of a vehicle or the like in which the input of a power source and a signal is integrated with a main body and is not assumed to be removed. For example, like a sash, No mention is made of the arrangement of the power supply unit, the control unit, and the like with respect to members that can be replaced independently.
　調光窓を、例えば引違い窓や上げ下げ窓のように窓自体が可動する可動窓に適用すれば、汎用性を大きく向上させることができる。 If the dimming window is applied to a movable window in which the window itself is movable, such as a sliding window or a raising / lowering window, versatility can be greatly improved.
　しかしながら、従来、引き違い窓のような可動式の窓について、電源部や制御部がどのように配置されているべきかについて、文献記載や実例がない。 However, conventionally, there is no literature description or examples of how the power supply unit and the control unit should be arranged for movable windows such as sliding windows.
　窓の框（サッシ）のように、調光対象となる窓ガラス等の透光性部材を組み込む組み込み部を有する支持体に電源部や制御部等を設けた場合、電源部や制御部が寿命や故障により動作不可能となった場合、框や、グレーチングチャンネルおよび框等を含む障子を分解して、電池交換や部品交換、修理等を行う必要がある。 If a power supply unit or control unit is provided on a support that has a built-in part that incorporates a light-transmitting member such as a window glass to be dimmed, such as a window sash, the power supply unit or control unit will have a lifetime. If it becomes impossible to operate due to a failure, it is necessary to disassemble the shoji, the grating channel and the shovel including the coffin, and replace the battery, replace the parts, and repair.
　しかしながら、このように框の分解を行うと、作業に非常に手間がかかる。また、調光窓に複層ガラスを用いる場合、ガラス間に埃やゴミが入り込む可能性がある。 However, when the soot is disassembled in this way, it takes a lot of work. In addition, when a double-glazed glass is used for the light control window, dust or dirt may enter between the glasses.
　本発明は、上記問題点に鑑みなされたものであり、その目的は、透光性部材を組み込む組み込み部を有する支持体に駆動装置を設けるとともに、上記組み込み部を分解することなく、駆動装置の修理や電池交換、部品交換等を行うことができる調光システムを提供することにある。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a drive device on a support body having a built-in portion into which a translucent member is incorporated and to dispose the drive device without disassembling the built-in portion. An object of the present invention is to provide a light control system capable of performing repair, battery replacement, parts replacement, and the like.
　上記の課題を解決するために、本発明の一態様にかかる調光システムは、透光性部材と、上記透光性部材に対向配置され、電圧を印加することで光の透過率を変化させる調光装置と、上記調光装置を駆動する駆動装置と、上記透光性部材および上記調光装置を組み込む組み込み部を有する支持体と、を備え、上記支持体の一部に、上記駆動装置の少なくとも一部を収容する収容部と、上記収容部を開閉自在に覆う開閉部と、が設けられている。 In order to solve the above-described problem, a light control system according to one embodiment of the present invention includes a light-transmitting member and a light-transmitting member that are disposed opposite to the light-transmitting member and change the light transmittance by applying a voltage. A light control device, a drive device that drives the light control device, and a support body that has a built-in portion that incorporates the translucent member and the light control device, and the drive device is provided on a part of the support body. A housing portion that houses at least a part of the housing portion, and an opening / closing portion that covers the housing portion so as to be freely opened and closed.
　本発明の一態様によれば、上記組み込み部を分解することなく、駆動装置の修理や電池交換、部品交換等を行うことができる調光システムを提供することができる。 According to one aspect of the present invention, it is possible to provide a light control system capable of repairing a drive device, replacing a battery, replacing parts, or the like without disassembling the above-described built-in portion.

That is, the dimming state of the dimming device 40 is automatically controlled according to the time schedule stored in the storage unit 53.
　また、調光装置４０を近赤外線調光装置（近赤外線調光部）とするときは、例えば各地域の天気や気温のインターネット上の情報を反映して近赤外線の室内への取り込みを制御してもよい。通信部５４は、通信装置６１、または、図示しない外部装置と無線でデータ通信が可能であり、例えばインターネット上に設置されたサーバ装置（情報配信サーバ、管理サーバ、外部装置）から、インターネット等の通信ネットワークを介して、調光装置４０（つまり、上記調光窓１）を設置する住所に対応する天気や気温等の気候情報をサービスとして配信し、これを通信装置６１、または、直接、通信部５４で受信し、調光装置４０の制御に反映することができる。すなわち、上記通信部５４は、外部の通信端末である通信装置６１を介して、または、直接、サーバ装置とデータ通信を行い、取得した情報を、調光装置４０の調光に利用することができる。 When the light control device 40 is a near-infrared light control device (near-infrared light control unit), for example, the information on the Internet on the weather and temperature of each region is reflected to control the incorporation of near-infrared light into the room. May be. The communication unit 54 can perform data communication wirelessly with the communication device 61 or an external device (not shown). For example, from a server device (information distribution server, management server, external device) installed on the Internet, the communication unit 54 Climate information such as weather and temperature corresponding to the address where the light control device 40 (that is, the light control window 1) is installed is distributed as a service via the communication network, and this is communicated with the communication device 61 or directly. It can be received by the unit 54 and reflected in the control of the light control device 40. That is, the communication unit 54 performs data communication with the server device directly or via the communication device 61 that is an external communication terminal, and uses the acquired information for dimming the dimming device 40. it can.
　制御部５２は、上記通信部５４を介して取得した上記気候情報に応じて、目的とする日射熱取得率（赤外線透過率）が得られるように、上記調光装置４０の駆動を制御する。 The control unit 52 controls driving of the light control device 40 so that a target solar heat acquisition rate (infrared transmittance) is obtained according to the climate information acquired via the communication unit 54.
　例えば、記憶部５３には、気候（天気、温度）と、調光装置４０に印加する電圧とを対応付けたＬＵＴ（Look Up Table：ルックアップテーブル）が記憶されている。制御部５２は、必要に応じて上記ＬＵＴを読み出すことで、上記ＬＵＴを用いて、電源部５１に印加すべき、上記通信部５４で取得した気候に応じた電圧を算出する。そして、目的とする日射熱取得率（赤外線透過率）が得られるように、電源部５１に、調光装置４０に印加する電圧を制御するための制御信号を送ることで、調光装置４０の調光を制御する。 For example, the storage unit 53 stores an LUT (Look Up Table) in which the climate (weather, temperature) and the voltage applied to the light control device 40 are associated with each other. The control unit 52 reads the LUT as necessary, and uses the LUT to calculate a voltage corresponding to the climate acquired by the communication unit 54 to be applied to the power supply unit 51. And the control signal for controlling the voltage applied to the light control apparatus 40 is sent to the power supply part 51 so that the target solar heat acquisition rate (infrared transmittance) may be obtained. Control dimming.
　また、通信装置６１または通信部５４を、インターネットに接続する代わりに、スマートメータに接続されたＨＥＭＳ（Home Energy Management System）に接続し、温度センサ等との組み合わせで室内温度や屋外温度や消費電力を管理し、調光装置４０の動作に反映させてもよい。ＨＥＭＳとは、各戸内の各家電における電力消費量の監視、節電のための各家電の制御、太陽光発電、燃料電池、蓄電器等の自家用電源の監視および制御、等を行う電力管理制御システム（外部装置）であり、予め設定された電力使用エリア内の電力使用量を管理し、制御する。すなわち、通信部５４は、ＨＥＭＳコントローラと接続することで、ＨＥＭＳによる管理・制御を行ってもよく、通信装置６１は、ＨＥＭＳコントローラそのものであってもよい。スマートメータは、通信機能を有する電力量計であり、スマートメータが計測した電力量は、計測日時と共に、ＨＥＭＳコントローラに送信される。ＨＥＭＳコントローラは、ユーザ宅の各家電（負荷機器）の電力消費量の監視、節電のための家電の制御等を行う制御機器である。 In addition, instead of connecting the communication device 61 or the communication unit 54 to the Internet, the communication device 61 or the communication unit 54 is connected to a HEMS (Home Energy Management System) connected to a smart meter and combined with a temperature sensor or the like, the indoor temperature, the outdoor temperature, and the power consumption May be managed and reflected in the operation of the light control device 40. HEMS is a power management control system that monitors the power consumption of each household appliance in each house, controls each household appliance for power saving, monitors and controls personal power sources such as solar power generation, fuel cells, and condensers ( An external device) that manages and controls the power consumption within a preset power usage area. That is, the communication unit 54 may perform management / control by HEMS by connecting to the HEMS controller, and the communication device 61 may be the HEMS controller itself. The smart meter is a watt-hour meter having a communication function, and the amount of power measured by the smart meter is transmitted to the HEMS controller together with the measurement date.

　＜調光装置４０＞
　次に、調光装置４０についてより詳細に説明する。 <Light control device 40>
Next, the light control device 40 will be described in more detail.
　（調光装置４０の種類）
　調光装置４０は、可視光を調光することで表示を切り替える表示部としてもよく、近赤外調光部とし、日射熱取得率を切り替えるようにしてもよい。 (Type of light control device 40)
The light control device 40 may be a display unit that switches display by adjusting visible light, or may be a near-infrared light control unit to switch the solar heat gain rate.
　なお、太陽からの赤外線の大部分は近赤外線であり、日射熱取得率を制御することと近赤外線透過率を制御することは、ほぼ等しい。また、冬場は室内から赤外線が屋外に出るのを防ぐ必要がある。しかし、このときの赤外線の波長は１０μｍ程度であり、遠赤外線に分類される。 It should be noted that most of the infrared rays from the sun are near-infrared rays, and controlling the solar heat acquisition rate is almost equal to controlling the near-infrared transmittance. In winter, it is necessary to prevent infrared rays from going out of the room. However, the wavelength of infrared rays at this time is about 10 μm, and is classified as far infrared rays.
　また、近赤外線透過の透明導電膜は、遠赤外線は反射するという特性を有する。すなわち、冬場に近赤外線を取り込むように調光装置４０を制御しても、室内の熱は輻射熱としては逃げないため、理想的な状態を得ることができる。なお、夏場に屋内に近赤外線が入らないように制御したときも、遠赤外線も同時に入らないため、理想的な状態を得ることができる。 Also, the near-infrared transparent conductive film has a characteristic of reflecting far-infrared rays. That is, even if the light control device 40 is controlled so as to capture near infrared rays in winter, the indoor heat does not escape as radiant heat, so that an ideal state can be obtained. Even when control is performed so that near infrared rays do not enter indoors in the summer, far infrared rays do not enter at the same time, so that an ideal state can be obtained.
　調光装置４０を表示部とする場合、調光装置４０としては、偏光板を用いた液晶表示装置、ゲストホスト型液晶表示装置、高分子分散型液晶表示装置、エレクトロクロミック表示装置、エレクトロウェッティング表示装置、有機ＥＬ（エレクトロルミネッセンス）表示装置あるいは無機ＥＬ表示装置等のＥＬ表示装置であってもよい。 When the light control device 40 is a display unit, the light control device 40 includes a liquid crystal display device using a polarizing plate, a guest-host liquid crystal display device, a polymer dispersion liquid crystal display device, an electrochromic display device, and electrowetting. It may be an EL display device such as a display device, an organic EL (electroluminescence) display device, or an inorganic EL display device.
　また、調光装置４０を近赤外調光部とする場合、調光方式としては、例えば、（１）近赤外反射または近赤外吸収を有する形状異方性部材を回転させることで調光する方式、（２）エレクトロクロミックにより発色と消色とを切り替える方式、（３）銀溶液のエレクトロクロミックで透明状態とミラー状態とを切り替える方式、（４）ＩＴＯ（tin doped indium oxide）やＡＺＯ（Aluminum doped Zinc Oxide）のナノ結晶による表面プラズモン共鳴の周波数を電圧印加で切り替えるエレクトロクロミック方式、（５）マグネシウム－ニッケル合金薄膜が接する中空層に水素を入れることで透明状態とミラー状態とを切り替えるガスクロミック方式等を用いることができる。 When the light control device 40 is a near-infrared light control unit, as the light control method, for example, (1) a shape anisotropic member having near-infrared reflection or near-infrared absorption is rotated to adjust light. (2) A method of switching between color development and decoloring by electrochromic, (3) A method of switching between a transparent state and a mirror state by electrochromic of silver solution, (4) ITO (tin doped indium oxide) and AZO Electrochromic method for switching the frequency of surface plasmon resonance by nanocrystals of (Aluminum doped Zinc Oxide) by applying voltage, (5) Switching between transparent state and mirror state by putting hydrogen into the hollow layer in contact with the magnesium-nickel alloy thin film A gas chromic method or the like can be used.
　なお、上記調光方式として、上記（５）に示すガスクロミック方式を用いる場合、収容部２６内に、図示しないガス発生部材を配置することで、電源部５１および制御部５２以外に、ガス発生部材も開閉部２７から修理・交換が可能となるように調光窓１が設計されていてもよい。 When the gas chromic method shown in (5) above is used as the dimming method, a gas generating member (not shown) is arranged in the accommodating portion 26, so that gas is generated in addition to the power source 51 and the controller 52. The dimming window 1 may be designed so that the member can be repaired and replaced from the opening / closing part 27.
　また、上記（１）に示す、形状異方性部材を回転させる調光方式を用いる場合、上記調光装置４０としては、例えば、可視光および近赤外光を吸収する針状結晶を回転させることにより、該針状結晶がランダムな状態と電界に平行な状態とで外光の吸収を切り替える、ＳＰＤ（Suspended Particle Device：懸濁粒子装置）を使用してもよい。また、ＳＰＤに代えて、形状異方性部材を回転させることで調光する方式を用いた調光装置を使用してもよい。 Moreover, when using the light control method which rotates a shape anisotropic member shown in said (1), as said light control apparatus 40, the needle crystal which absorbs visible light and near-infrared light is rotated, for example. Thus, an SPD (Suspended Particle Device) that switches absorption of external light between a random state and a state parallel to the electric field may be used. Moreover, it may replace with SPD and may use the light control apparatus using the system which light-controls by rotating a shape anisotropic member.
　（調光装置４０の概略構成）
　以下では、調光装置４０が、形状異方性部材を回転させることで調光する調光方式を用いた近赤外調光装置（近赤外調光部）である場合を例に挙げて、調光装置４０の概略構成について、より具体的に説明する。しかしながら、本実施形態は、これに限定されるものではなく、上記調光装置４０としては、上述したように、調光機能を有する公知の各種装置を使用することができる。 (Schematic configuration of the light control device 40)
Below, the case where the light control apparatus 40 is a near-infrared light control apparatus (near-infrared light control part) using the light control system which light-controls by rotating a shape anisotropic member is mentioned as an example. The schematic configuration of the light control device 40 will be described more specifically. However, the present embodiment is not limited to this, and as the light control device 40, various known devices having a light control function can be used as described above.
　図３は、本実施形態にかかる調光窓１における窓本体ユニット１０の要部の概略構成を示す他の断面図である。また、図４の（ａ）は、本実施形態にかかる調光装置４０の概略構成の一例を示す断面図であり、図４の（ｂ）は、本実施形態にかかる調光装置４０で使用される形状異方性部材１３２の一例を示す斜視図である。 FIG. 3 is another cross-sectional view showing a schematic configuration of a main part of the window main body unit 10 in the light control window 1 according to the present embodiment. 4A is a cross-sectional view illustrating an example of a schematic configuration of the light control device 40 according to the present embodiment, and FIG. 4B is used in the light control device 40 according to the present embodiment. It is a perspective view which shows an example of the shape anisotropic member 132 used.
　調光装置４０は、図１の（ｂ）および図３に示すように、互いに対向して配置された一対の基板１１０・１２０と、これら一対の基板１１０・１２０間に配置された光変調層１３０（調光層）と、を備えた調光セルである。 As shown in FIG. 1B and FIG. 3, the light control device 40 includes a pair of substrates 110 and 120 disposed to face each other, and a light modulation layer disposed between the pair of substrates 110 and 120. 130 (light control layer).
　基板１１０は、絶縁性基板１１１と電極１１２とを備えている。同様に、基板１２０は、絶縁性基板１２１と電極１２２とを備えている。 The substrate 110 includes an insulating substrate 111 and an electrode 112. Similarly, the substrate 120 includes an insulating substrate 121 and an electrode 122.
　光変調層１３０は、電極１１２・１２２間に設けられ、媒体１３１と、媒体１３１に含有される複数の形状異方性部材１３２とを備えている。 The light modulation layer 130 is provided between the electrodes 112 and 122 and includes a medium 131 and a plurality of shape anisotropic members 132 contained in the medium 131.
　絶縁性基板１１１・１２１には、例えば、透明なガラス基板あるいはプラスチック基板が用いられる。 As the insulating substrates 111 and 121, for example, a transparent glass substrate or a plastic substrate is used.
　なお、絶縁性基板１１１・１２１にガラス基板を用いる場合には、熱割れを防止するために、ガラスエッジはクリーンカットされており、研磨等により面取りを行っていてもよい。また、ガラス基板の熱割れを防止するために、ガラス基板と框２０（サッシ）とのクリアランスを確保した上で、該ガラス基板を、弾性シーリング材で保持することが好ましい。 In addition, when using a glass substrate for the insulating substrates 111 and 121, in order to prevent thermal cracking, the glass edge is clean-cut and may be chamfered by polishing or the like. In order to prevent thermal cracking of the glass substrate, it is preferable to secure the clearance between the glass substrate and the ridge 20 (sash) and hold the glass substrate with an elastic sealing material.
　電極１１２・１２２は、透明電極であり、例えば、ＩｎＴｉＯ（Titanium doped indium oxide）や、アナターゼ型二酸化チタンをシード層としたタンタル置換酸化スズ、ＩＴＯ（Indium Tin Oxide）、ＩＺＯ（Indium Zinc Oxide）、酸化亜鉛、酸化スズ等の透明導電膜により形成されている。 The electrodes 112 and 122 are transparent electrodes, for example, InTiO (Titanium doped indium oxide), tantalum-substituted tin oxide using anatase-type titanium dioxide as a seed layer, ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), It is formed of a transparent conductive film such as zinc oxide or tin oxide.
　本実施形態では、調光装置４０を調光窓１の調光に使用することから、電極１１２・１２２としては、形状異方性部材１３２を、その近赤外光反射面が基板１１０・１２０の基板面に垂直に配向されるときになるべく高い近赤外光透過率を得るために、近赤外光吸収の少ない電極、さらに好ましくは、窓としての機能を持たせるため可視光吸収の少ない電極が好適に用いられる。 In this embodiment, since the light control device 40 is used for light control of the light control window 1, as the electrodes 112 and 122, the shape anisotropic member 132 is used, and the near infrared light reflection surface thereof is the substrate 110 or 120. In order to obtain as high a near-infrared light transmittance as possible when oriented perpendicular to the substrate surface of the substrate, it is preferable that the electrode has little near-infrared light absorption, and more preferably has little visible light absorption to provide a window function. An electrode is preferably used.
　また、基板１１０・１２０のうち一方の基板における、他の基板との対向面には、スペーサ１４１が設けられている。基板１１０・１２０間にスペーサ１４１を設けることで、基板１１０・１２０間のセル厚を一定に保つことができる。また、図１の（ｂ）に示すように基板１１０・１２０を立てて設置する際に、媒体１３１よりも比重が大きい形状異方性部材１３２が沈降してしまい、基板面内の分布が偏ってしまうことを防ぐことができる。 Further, a spacer 141 is provided on the surface of one of the substrates 110 and 120 facing the other substrate. By providing the spacer 141 between the substrates 110 and 120, the cell thickness between the substrates 110 and 120 can be kept constant. In addition, when the substrates 110 and 120 are installed upright as shown in FIG. 1B, the shape anisotropic member 132 having a specific gravity larger than that of the medium 131 is settled, and the distribution in the substrate surface is uneven. Can be prevented.
　基板１１０と基板１２０とは、両基板１１０・１２０の周縁部に設けられたシール材１４２で互いに貼り合わされている。 The substrate 110 and the substrate 120 are bonded to each other with a sealing material 142 provided on the peripheral portions of both the substrates 110 and 120.
　シール材１４２としては、例えば、ＵＶ（紫外線）硬化型の樹脂が好適に使用される。また、シール材１４２として、媒体１３１と接する内側には耐溶剤性のあるシール材を形成し、その外側に、接着力の強いシール材をさらに形成しておくことがより望ましい。 As the sealing material 142, for example, a UV (ultraviolet) curable resin is preferably used. It is more desirable to form a solvent-resistant seal material on the inner side in contact with the medium 131 as the seal material 142 and further form a seal material having a strong adhesive force on the outer side.
　形状異方性部材１３２の形状としては、例えば、フレーク状、円柱状、あるいは楕円球状等を採用することができる。 As the shape of the shape anisotropic member 132, for example, a flake shape, a columnar shape, or an elliptical sphere shape can be adopted.
　図４の（ｂ）では、形状異方性部材１３２として、フレーク（フレーク状の粒子）を例に挙げて図示している。 In FIG. 4B, flakes (flaky particles) are shown as an example of the shape anisotropic member 132.
　上記フレークとしては、例えば、透過率を変更すべき波長が近赤外光である場合、近赤外反射特性を有する材料のフレーク、近赤外反射特性を有する材料をガラスや雲母等のベースフレークに設けたフレーク、ベースフレークに酸化チタン等の高屈折率層を形成し、その膜厚やベースフレークの厚さに依存する干渉光を近赤外光になるようにしたフレーク、近赤外線に表面プラズモン共鳴の吸収を持つ、例えば銀等のフレーク等を用いることができる。 As the flakes, for example, when the wavelength whose transmittance is to be changed is near-infrared light, flakes of materials having near-infrared reflection characteristics, and materials having near-infrared reflection characteristics are made of base flakes such as glass and mica The surface of the flakes and near infrared rays are formed with a high refractive index layer such as titanium oxide formed on the flakes and base flakes, and the interference light depending on the film thickness and the thickness of the base flakes becomes near infrared light. For example, flakes such as silver having plasmon resonance absorption can be used.
　なお、図４の（ｂ）では、上記形状異方性部材１３２（フレーク）として、近赤外反射特性を有する近赤外反射材料からなる近赤外反射層１３４がガラス層１３３上に設けられたフレークを例に挙げて図示している。 In FIG. 4B, a near-infrared reflective layer 134 made of a near-infrared reflective material having near-infrared reflective properties is provided on the glass layer 133 as the shape anisotropic member 132 (flakes). The flakes are shown as an example.
　上述したように調光装置４０が近赤外調光装置である場合、形状異方性部材１３２は、例えば、その近赤外反射層１３４（近赤外光反射面）が、基板１１０・１２０の基板面に略平行に配向されるときに正反射が得られる形状および大きさ（径）を有していることが好ましい。本実施形態では、一例として、後述するように、約３５μｍ厚のガラス層１３３上に近赤外反射材料を蒸着し、これを粉砕することにより、約１２０μｍ径のフレークを作製した。 As described above, when the light control device 40 is a near-infrared light control device, the shape anisotropic member 132 has, for example, the near-infrared reflection layer 134 (near-infrared light reflection surface) of the substrate 110 or 120. It is preferable to have a shape and a size (diameter) at which regular reflection can be obtained when oriented substantially parallel to the substrate surface. In this embodiment, as an example, as described later, a near-infrared reflective material is vapor-deposited on a glass layer 133 having a thickness of about 35 μm, and pulverized to produce flakes having a diameter of about 120 μm.
　なお、上述したように調光装置４０が近赤外調光装置である場合、形状異方性部材１３２は、可視光領域に対しては吸収や反射があってもよいが、なくてもよい。吸収や反射がない状態、すなわち、目視状態で概ね透明であれば、調光窓１を近赤外遮断状態にしても透過状態にしても概ね透明であり、現在窓が設けられている建物や乗り物等において、該窓を、機能性を有する窓として、調光窓１と置き換えることが可能である。 As described above, when the light control device 40 is a near-infrared light control device, the shape anisotropic member 132 may or may not absorb or reflect in the visible light region. . If there is no absorption or reflection, that is, if it is almost transparent in the visual state, it is almost transparent even if the dimming window 1 is in the near-infrared blocking state or in the transmitting state. In a vehicle or the like, the window can be replaced with a dimming window 1 as a window having functionality.
　また、形状異方性部材１３２の比重は、例えば、媒体１３１と同等の比重であることが望ましい。比重の大きな中心材料に対して、樹脂等の比重の小さい材料を被覆するときは、被覆物の膜厚により、形状異方性部材１３２の平均的な比重を調整することが可能である。形状異方性部材１３２の比重が媒体１３１に比べて大きく異なるときは、形状異方性部材１３２が沈降するという問題がある。 Further, the specific gravity of the shape anisotropic member 132 is preferably the same specific gravity as that of the medium 131, for example. When a material having a small specific gravity such as a resin is coated on a central material having a large specific gravity, the average specific gravity of the shape anisotropic member 132 can be adjusted by the film thickness of the covering. When the specific gravity of the shape anisotropic member 132 is significantly different from that of the medium 131, there is a problem that the shape anisotropic member 132 sinks.
　媒体１３１は、ガラスよりも比誘電率の高いものであればよく、好ましくは比誘電率２０以上がよい。 The medium 131 only needs to have a relative dielectric constant higher than that of glass, and preferably has a relative dielectric constant of 20 or more.
　窓としての機能を持たせるため、媒体１３１には、例えば、可視光領域において透過性を有する材料であり、可視光領域において概ね吸収のない液体や、それらを色素で着色したもの等が用いられる。また、媒体１３１の比重は、形状異方性部材１３２と同等であることが好ましい。 In order to provide a function as a window, the medium 131 is, for example, a material that is transmissive in the visible light region, a liquid that does not substantially absorb in the visible light region, or a material that is colored with a pigment. . Further, the specific gravity of the medium 131 is preferably equivalent to that of the shape anisotropic member 132.
　また、媒体１３１は、単一の物質で形成されていてもよく、複数の物質の混合物で形成されていてもよい。媒体１３１としては、例えば、炭酸プロピレン、ＮＭＰ（Ｎ－メチル－２－ピロリドン）、フルオロカーボン、シリコーンオイル等を用いることができる。 Further, the medium 131 may be formed of a single substance or a mixture of a plurality of substances. As the medium 131, for example, propylene carbonate, NMP (N-methyl-2-pyrrolidone), fluorocarbon, silicone oil, or the like can be used.
　上述したように調光装置４０が近赤外調光装置である場合、媒体１３１としては、電極１１２・１２２同様、近赤外領域の吸収は弱い方がよい。また、媒体１３１の粘度が高いと、形状異方性部材１３２の状態を保持できる一方、駆動電圧が高くなるおそれがある。本実施形態にかかる調光システムが上述したように調光窓１である場合、その動作回数は１日に数回程度のものであり、仮に駆動電圧が高くても形状異方性部材１３２の状態を保持できることが低消費電力化に有利である場合は、媒体１３１として、形状異方性部材１３２の状態を保持できる粘度のものを用いることができる。なお、粘度を高めるには、シリコーンオイルやポリエチレングリコール等の単体で粘度が高い媒体を用いる他、ＰＭＭＡ（ポリメタクリル酸メチル）等を混合させたり、シリカ微粒子等のチキソ性を発現する材料を混合させたりしてもよい。 As described above, when the light control device 40 is a near-infrared light control device, it is preferable that the medium 131 has a weak absorption in the near-infrared region, like the electrodes 112 and 122. Further, when the viscosity of the medium 131 is high, the state of the shape anisotropic member 132 can be maintained, while the drive voltage may be increased. When the light control system according to the present embodiment is the light control window 1 as described above, the number of operations is about several times a day, and even if the drive voltage is high, the shape anisotropic member 132 In the case where maintaining the state is advantageous for reducing power consumption, a medium 131 having a viscosity capable of maintaining the state of the shape anisotropic member 132 can be used. In order to increase the viscosity, in addition to using a single high viscosity medium such as silicone oil or polyethylene glycol, PMMA (polymethyl methacrylate) or the like is mixed, or thixotropic material such as silica fine particles is mixed. You may let them.
　＜調光装置４０の製造方法＞
　以下に、本実施形態にかかる調光装置４０の製造方法の一例について、その材料と併せて具体的に説明する。 <Method for Manufacturing Light Control Device 40>
Below, an example of the manufacturing method of the light modulation apparatus 40 concerning this embodiment is demonstrated concretely with the material.
　本実施形態では、約３５μｍのガラス層１３３上に、近赤外反射層１３４として、近赤外反射特性を有するＩＴＯ（Indium Tin Oxide）を蒸着し、これを粉砕することにより、形状異方性部材１３２として、約１２０μｍ径のフレークを作製した。 In this embodiment, ITO (Indium Tin Oxide) having near-infrared reflection characteristics is vapor-deposited as a near-infrared reflection layer 134 on a glass layer 133 of about 35 μm and pulverized to form shape anisotropy. As the member 132, a flake having a diameter of about 120 μm was produced.
　一方、絶縁性基板１１１・１２１としてガラス基板を使用し、該ガラス基板に、電極１１２・１２２として、ＩｎＴｉＯ（Titanium doped indium oxide）やアナターゼ型二酸化チタンをシード層としたタンタル置換酸化スズ等の、近赤外線を透過する透明導電膜を形成することにより、一対の基板１１０・１２０を作製した。 On the other hand, a glass substrate is used as the insulating substrates 111 and 121, and tantalum substituted tin oxide using InTiO (Titanium doped indium oxide) or anatase type titanium dioxide as a seed layer as the electrodes 112 and 122, etc. A pair of substrates 110 and 120 was manufactured by forming a transparent conductive film that transmits near infrared rays.
　なお、基板１１０・１２０のうち一方の基板には、セル厚を確保するために、スペーサ１４１を設けておくことが好ましい。そこで、本実施形態では、基板１１０・１２０のうち一方の基板に、例えば２００μｍ、高さ２００μｍのスペーサ１４１を、フォトリソグラフィにより形成した。 In addition, it is preferable to provide a spacer 141 on one of the substrates 110 and 120 in order to ensure the cell thickness. Therefore, in this embodiment, the spacer 141 having a thickness of 200 μm and a height of 200 μm, for example, is formed on one of the substrates 110 and 120 by photolithography.
　次いで、炭酸プロピレンを媒体１３１とし、該媒体１３１に、形状異方性部材１３２として上記フレークを例えば２０ｗｔ％の割合で分散させた分散液（フレーク混合液）を、基板１１０・１２０のうち、シール材１４２を形成した、一方の基板上に滴下した。 Next, propylene carbonate is used as the medium 131, and a dispersion liquid (flakes mixed liquid) in which the flakes are dispersed in the medium 131 as the shape anisotropic member 132 at a ratio of, for example, 20 wt% is sealed in the substrates 110 and 120. The material 142 was dropped on one substrate on which the material 142 was formed.
　なお、上記分散液を滴下する基板には、シール材１４２として、例えばＵＶ硬化型の樹脂が形成されていることが好ましく、さらに好ましくは、媒体１３１と接する内側には耐溶剤性のあるシール材が形成され、その外側に、接着力の強いシール材が形成されていることが望ましい。 Note that, for example, a UV curable resin is preferably formed as the sealing material 142 on the substrate on which the dispersion liquid is dropped, and more preferably, a solvent-resistant sealing material is formed on the inner side in contact with the medium 131. It is desirable that a sealing material having a strong adhesive force is formed outside.
　上記２枚の基板１１０・１２０を貼り合せた後、シール材１４２を硬化させることで、本実施形態にかかる調光装置４０を作製した。 After bonding the two substrates 110 and 120, the dimmer 40 according to the present embodiment was manufactured by curing the sealing material 142.
　なお、媒体１３１には、例えばシリカ微粒子を分散させる等の手法によりチキソトロピーを持たせてもよい。これにより、フレークの沈降を抑制できるとともに、動作状態にメモリ性を持たせ、電圧の印加頻度を下げることで、消費電力を低減することができる。 Note that the medium 131 may have thixotropy by, for example, a technique of dispersing silica fine particles. Thereby, the sedimentation of flakes can be suppressed, and the power consumption can be reduced by giving the operation state memory characteristics and reducing the voltage application frequency.
　＜光変調層１３０の近赤外光の透過率制御＞
　次に、光変調層１３０による近赤外光の透過率の制御方法について、図５の（ａ）・（ｂ）を参照して具体的に説明する。ここでは、形状異方性部材１３２としてフレークを使用し、電圧により、フレークの配向状態を基板１１０・１２０に平行な状態と基板１１０・１２０に垂直な状態とで切り替えることで近赤外光の透過率を変更する場合について説明する。 <Near-infrared light transmittance control of light modulation layer 130>
Next, a method for controlling the transmittance of near-infrared light by the light modulation layer 130 will be specifically described with reference to FIGS. Here, flakes are used as the shape-anisotropic member 132, and the orientation state of the flakes is switched between a state parallel to the substrates 110 and 120 and a state perpendicular to the substrates 110 and 120 by voltage. A case where the transmittance is changed will be described.
　図５の（ａ）は、近赤外光反射状態を示す図であり、図５の（ｂ）は、近赤外光透過状態を示す図である。 5A is a diagram showing a near-infrared light reflection state, and FIG. 5B is a diagram showing a near-infrared light transmission state.
　対向する電極１１２・１２２間に、例えば２Ｖの直流電圧（周波数＝０Ｈｚ）を印加すると、帯電したフレーク（形状異方性部材１３２）が電気泳動により一方の電極に集まるため、近赤外光反射状態が得られる。なお、このとき、電極１１２・１２２間に、直流電圧に代えて、例えば、１Ｈｚ以下の低周波の交流を印加することにより、いわゆる焼き付きを回避するようにしてもよい。 When, for example, a DC voltage of 2 V (frequency = 0 Hz) is applied between the opposing electrodes 112 and 122, the charged flakes (shape anisotropic member 132) are collected on one electrode by electrophoresis, so that near-infrared light reflection occurs. A state is obtained. At this time, so-called burn-in may be avoided by applying a low-frequency alternating current of 1 Hz or less, for example, between the electrodes 112 and 122 instead of the direct-current voltage.
　なお、図５の（ａ）では、フレークが、屋外側の基板１１０における電極１１２に貼り付くように配向した例を示している。図５の（ａ）では、電源部５１のプラス側を電極１１２に接続し、電源部５１のマイナス側を電極１２２に接続しているが、これに限定されず、電源部５１のマイナス側を電極１１２に接続し、電源部５１のプラス側を電極１２２に接続してもよい。電源部５１のマイナス側を電極１１２に接続し、電源部５１のプラス側を電極１２２に接続した場合、フレークは、基板１２０に貼り付くように配向する。また、図５の（ａ）では、フレークに帯電する電荷の極性が負の場合を示しているが、これに限定されず、フレークに帯電する電荷の極性が正であってもよい。この場合にも、フレークが貼り付く基板が、図５の（ａ）の場合とは逆になる。 FIG. 5A shows an example in which flakes are oriented so as to stick to the electrodes 112 on the substrate 110 on the outdoor side. In FIG. 5A, the positive side of the power supply unit 51 is connected to the electrode 112, and the negative side of the power supply unit 51 is connected to the electrode 122. However, the present invention is not limited to this. It may be connected to the electrode 112, and the positive side of the power supply unit 51 may be connected to the electrode 122. When the negative side of the power supply unit 51 is connected to the electrode 112 and the positive side of the power supply unit 51 is connected to the electrode 122, the flakes are oriented so as to stick to the substrate 120. 5A shows a case where the polarity of the electric charge charged to the flakes is negative, the present invention is not limited to this, and the polarity of the electric charge charged to the flakes may be positive. Also in this case, the substrate to which the flakes are attached is opposite to the case of FIG.
　このように、光変調層１３０に、周波数が０Ｈｚとなる直流、または、周波数が１Ｈｚ以下の低周波の交流を印加すると、電気泳動力やクーロン力で説明される力により、帯電性を有するフレークは、その帯電した電荷の極性と逆極性の電荷が帯電された電極付近に吸い寄せられる。そして、フレークは、最も安定した配向をとり、基板１１０または基板１２０に貼り付くように回転する。このように、フレークが、その長軸が基板１１０・１２０に平行になるように配向することで、基板１１０側から光変調層１３０へ入射された光は、フレークにより遮断され、光変調層１３０を透過（通過）しない。 As described above, when a direct current having a frequency of 0 Hz or a low-frequency alternating current having a frequency of 1 Hz or less is applied to the light modulation layer 130, the flakes having chargeability are generated by the force explained by the electrophoretic force or the Coulomb force. Is attracted to the vicinity of the charged electrode with a charge having a polarity opposite to that of the charged charge. The flakes take the most stable orientation and rotate to stick to the substrate 110 or the substrate 120. In this way, the flakes are oriented so that their long axes are parallel to the substrates 110 and 120, so that light incident on the light modulation layer 130 from the substrate 110 side is blocked by the flakes, and the light modulation layer 130 Does not pass through.
　一方、対向する電極１１２・１２２間に、例えば６０Ｈｚ、５Ｖの高周波の交流電圧を印加すると、誘電泳動現象、クーロン力または電気エネルギー的な観点から説明される力により、フレークは、図５の（ｂ）に示すように、基板１１０・１２０に垂直な方向に動作し、近赤外光透過状態が得られる。 On the other hand, when a high-frequency AC voltage of, for example, 60 Hz and 5 V is applied between the opposing electrodes 112 and 122, the flakes are caused by the dielectrophoresis phenomenon, the Coulomb force, or the force explained from the viewpoint of electric energy, as shown in ( As shown in b), it operates in a direction perpendicular to the substrates 110 and 120, and a near-infrared light transmission state is obtained.
　つまり、光変調層１３０に、高周波として例えば周波数６０Ｈｚの交流電圧を印加すると、フレークは、その長軸が電気力線に平行になるように回転する。すなわち、フレークは、その長軸が基板１１０・１２０に垂直になるように配向する。これにより、基板１１０側から光変調層１３０へ入射された光は、光変調層１３０を透過（通過）して、基板１２０側から出射される。 That is, when an AC voltage having a frequency of 60 Hz, for example, is applied to the light modulation layer 130 as a high frequency, the flakes rotate so that the major axis thereof is parallel to the lines of electric force. That is, the flakes are oriented so that their long axes are perpendicular to the substrates 110 and 120. Thereby, the light incident on the light modulation layer 130 from the substrate 110 side is transmitted (passed) through the light modulation layer 130 and emitted from the substrate 120 side.
　なお、形状異方性部材１３２の配向状態が切り替わる周波数は、形状異方性部材１３２の形状および材質、光変調層１３０の厚み（セル厚）等により、予め設定される。 It should be noted that the frequency at which the orientation state of the shape anisotropic member 132 is switched is set in advance depending on the shape and material of the shape anisotropic member 132, the thickness (cell thickness) of the light modulation layer 130, and the like.
　図６の（ａ）・（ｂ）は、実際に作製した調光装置４０（調光セル）における対向する電極１１２・１２２間に電圧を印加したときの平面視でのフレークの配向状態を撮影した顕微鏡写真を示す図であり、図６の（ａ）は、上記電極１１２・１２２間に２Ｖの直流電圧を印加したときを示し、図６の（ｂ）は、上記電極１１２・１２２間に、６０Ｈｚ、５Ｖの交流電圧を印加したときを示す。なお、ここでは、前述した製造方法にしたがって調光装置４０を作製した。 6A and 6B are photographs of flake orientation in a plan view when a voltage is applied between the opposing electrodes 112 and 122 in the light control device 40 (light control cell) actually manufactured. FIG. 6A shows a case where a DC voltage of 2 V is applied between the electrodes 112 and 122, and FIG. 6B shows a state between the electrodes 112 and 122. , 60 Hz, 5 V when an AC voltage is applied. In addition, here, the light control apparatus 40 was produced according to the manufacturing method mentioned above.
　図６の（ａ）に示すように、上記電極１１２・１２２間に直流電圧を印加した場合、フレークは基板１１０・１２０と平行な方向に概ね配向している。このため、調光セルに入射した近赤外光は、光の入射側に反射される。 As shown in FIG. 6A, when a DC voltage is applied between the electrodes 112 and 122, the flakes are generally oriented in a direction parallel to the substrates 110 and 120. For this reason, the near-infrared light which entered into the light control cell is reflected by the incident side of light.
　一方、図６の（ｂ）に示すように、上記電極１１２・１２２間に、高周波の交流電圧を印加した場合、フレークが基板１１０・１２０に垂直な方向に配向する。このため、図６の（ｂ）では、平面視で、フレークの断面が見えている。このため、調光セルに入射した近赤外光は、光の入射側とは反対側に向かって調光セルを透過する。 On the other hand, as shown in FIG. 6B, when a high-frequency AC voltage is applied between the electrodes 112 and 122, the flakes are oriented in a direction perpendicular to the substrates 110 and 120. For this reason, in FIG.6 (b), the cross section of flakes can be seen by planar view. For this reason, the near-infrared light incident on the dimming cell passes through the dimming cell toward the side opposite to the light incident side.
　本実施形態では、前述したように、調光装置４０は、屋外側に基板１１０が配置され、屋内側に基板１２０が配置されている。このため、図５の（ａ）および図６の（ａ）に示す近赤外光反射状態では、屋外から入射した近赤外光は、調光装置４０内の形状異方性部材１３２のフレーク面で正反射し、効率的に入射側に反射される。 In this embodiment, as described above, in the light control device 40, the substrate 110 is disposed on the outdoor side, and the substrate 120 is disposed on the indoor side. Therefore, in the near-infrared light reflection state shown in FIGS. 5A and 6A, near-infrared light incident from the outside is flakes of the shape anisotropic member 132 in the light control device 40. The light is regularly reflected on the surface and efficiently reflected on the incident side.
　一方、図５の（ｂ）および図６の（ｂ）に示す近赤外光透過状態では、屋外から入射した近赤外光は、屋内側に透過する。このとき、上記近赤外光透過状態では、屋外からの近赤外光は、図５の（ｂ）に示すように基板１１０の基板面（入射側）に斜め方向から入射されても、形状異方性部材１３２のフレーク面によって反射され、屋内側の基板１２０に入射される。 On the other hand, in the near-infrared light transmission state shown in FIGS. 5B and 6B, near-infrared light incident from the outside is transmitted indoors. At this time, in the near-infrared light transmission state, even if the near-infrared light from the outside is incident on the substrate surface (incident side) of the substrate 110 from an oblique direction as shown in FIG. The light is reflected by the flake surface of the anisotropic member 132 and is incident on the indoor-side substrate 120.
　＜形状異方性部材１３２の配向のタイムスケジュール＞
　上述したように形状異方性部材１３２の配向状態を、基板１１０・１２０に平行な状態と基板１１０・１２０に垂直な状態とで切り替えることで近赤外光反射状態と近赤外光透過状態とを切り替える場合、調光装置４０は、通信部５４あるいはスイッチ部５５からの信号に基づいて近赤外光反射状態と近赤外光透過状態とを切り替えるようにしてもよいし、予め設定したタイムスケジュールに応じて近赤外光反射状態と近赤外光透過状態とを切り替えるようにしてもよい。 <Time schedule of orientation of shape anisotropic member 132>
As described above, the near-infrared light reflection state and the near-infrared light transmission state are achieved by switching the orientation state of the shape anisotropic member 132 between a state parallel to the substrates 110 and 120 and a state perpendicular to the substrates 110 and 120. The light control device 40 may switch between the near-infrared light reflection state and the near-infrared light transmission state based on a signal from the communication unit 54 or the switch unit 55, or may be set in advance. You may make it switch a near-infrared-light reflective state and a near-infrared-light transmissive state according to a time schedule.
　後者の場合、例えば、制御部５２は、記憶部５３に記憶されたタイムスケジュールに基づいて、形状異方性部材１３２の配向状態を制御する。つまり、形状異方性部材１３２の配向状態は、記憶部５３に記憶されたタイムスケジュールに沿って自動的に制御される。 In the latter case, for example, the control unit 52 controls the orientation state of the shape anisotropic member 132 based on the time schedule stored in the storage unit 53. That is, the orientation state of the shape anisotropic member 132 is automatically controlled according to the time schedule stored in the storage unit 53.
　具体的には、電源部５１を制御して、調光装置４０に電圧を印加することで、上記形状異方性部材１３２の上記一対の基板１１０・１２０への投影面積を変化させて、近赤外光の反射状態と透過状態との切り替えを制御する。この制御を上記タイムスケジュールに応じて実行する。 Specifically, by controlling the power supply unit 51 and applying a voltage to the light control device 40, the projected area of the shape anisotropic member 132 onto the pair of substrates 110 and 120 is changed, and the proximity is changed. Controls switching between the reflection state and transmission state of infrared light. This control is executed according to the time schedule.
　＜調光装置４０の配置＞
　前述したように、調光装置４０は、グレーチングチャンネル３１により、框２０の組み込み部２４に設けられた凹部２５内に固定されることで、框２０の枠内に保持される。 <Arrangement of light control device 40>
As described above, the light control device 40 is held in the frame of the basket 20 by being fixed in the recess 25 provided in the built-in part 24 of the basket 20 by the grating channel 31.
　調光装置４０は、窓ガラス１１の板面に垂直な方向から見たときに、窓ガラス１１の板面に重畳するように、窓ガラス１１に対向配置される。 The light control device 40 is disposed to face the window glass 11 so as to overlap the plate surface of the window glass 11 when viewed from a direction perpendicular to the plate surface of the window glass 11.
　このとき、調光装置４０は、図３に示すように、例えば、糊剤やＵＶ硬化樹脂等の接着剤層７２（貼着層）で窓ガラス１１に貼り付けられていてもよい。 At this time, as shown in FIG. 3, the light control device 40 may be attached to the window glass 11 with an adhesive layer 72 (adhesion layer) such as a glue or a UV curable resin, for example.
　なお、絶縁性基板１１１・１２１がプラスチック基板で形成されていると、調光装置４０を少し反らしながら窓ガラス１１に貼り付けることができる。このため、この場合、調光装置４０を、気泡が噛まないように窓ガラス１１に貼り付け易いという利点がある。 If the insulating substrates 111 and 121 are formed of a plastic substrate, the light control device 40 can be attached to the window glass 11 while being slightly warped. For this reason, in this case, there is an advantage that the light control device 40 can be easily attached to the window glass 11 so that bubbles are not bitten.
　また、上述したように、調光装置４０が、シール材１４２で貼り合わされた一対の基板１１０・１２０を備えている場合、シール材１４２は、図３に示すように、グレーチングチャンネル３１と対向する位置に配置されていることが好ましい。これにより、一対の基板１１０・１２０間に、シール材１４２として、例えば、強度が強い樹脂製シール材が存在する部分にグレーチングチャンネル３１の圧力がかかるように調光装置４０を設置することができる。さらに、シール材１４２が外部から見えないことにより、意匠性の高い調光窓１を形成することができる。 In addition, as described above, when the light control device 40 includes the pair of substrates 110 and 120 bonded together with the sealing material 142, the sealing material 142 faces the grating channel 31 as shown in FIG. It is preferable to arrange in the position. Thereby, the light control device 40 can be installed between the pair of substrates 110 and 120 so that the pressure of the grating channel 31 is applied, for example, to a portion where the sealing material 142 having a strong resin sealing material exists. . Furthermore, since the sealing material 142 is not visible from the outside, the light control window 1 with high designability can be formed.
　なお、図示はしないが、調光装置４０は、シール材１４２が、グレーチングチャンネル３１よりも窓本体ユニット１０の内側、すなわち、框２０の内側に、グレーチングチャンネル３１と対向しないように配置されていてもよい。 Although not shown, the light control device 40 is arranged so that the sealing material 142 does not face the grating channel 31 inside the window body unit 10, that is, inside the tub 20, rather than the grating channel 31. Also good.
　シール材１４２の外側には、光変調層１３０は存在しない。このため、シール材１４２をグレーチングチャンネル３１よりも框２０の枠の内側（つまり、中央寄り）に配置することで、グレーチングチャンネル３１の圧力がかかる部分は、一対の基板１１０・１２０のうち一方の基板のみが形成された構成とするか、もしくは、配線７１または配線用のフレキシブル基板が配置されるように調光装置４０を形成することができる。 The light modulation layer 130 does not exist outside the sealing material 142. For this reason, by arranging the sealing material 142 on the inner side (that is, closer to the center) of the frame of the flange 20 than the grating channel 31, the portion to which the pressure of the grating channel 31 is applied is one of the pair of substrates 110 and 120. The light control device 40 can be configured such that only the substrate is formed, or the wiring 71 or the flexible substrate for wiring is arranged.
　＜電極１１２・１２２の変形例＞
　調光装置４０を近赤外線調光部のように表示を目的としないようなものとした場合、１つの透明電極に対して、電極取出し部は、一個所であってもよく、複数個所であってもよい。 <Modification of electrodes 112 and 122>
When the light control device 40 is not intended for display like the near-infrared light control unit, there may be one electrode extraction unit or a plurality of electrode extraction units with respect to one transparent electrode. May be.
　１つの透明電極に対して、電極取出し部が一個所である場合は、調光装置４０の組立工程が簡略化されるとともに、配線７１の引き回しを簡素にすることができる。 When there is one electrode extraction part for one transparent electrode, the assembly process of the light control device 40 can be simplified and the routing of the wiring 71 can be simplified.
　一方、電極取出し部を複数個所設けた場合には、例えば調光装置４０の光変調層１３０（調光層）に抵抗成分がある場合（すなわち、電流が流れるような場合）にも、配線７１の接続部分から遠い場所の光変調層１３０の動作を確実にでき、部分的な応答速度の遅延を防ぐことができる。 On the other hand, when a plurality of electrode extraction portions are provided, for example, when the light modulation layer 130 (light control layer) of the light control device 40 has a resistance component (that is, when current flows), the wiring 71 Thus, the operation of the light modulation layer 130 at a location far from the connection portion of the first and second connection portions can be ensured, and a partial response speed delay can be prevented.
　例えば、光変調層１３０における媒体１３１として電気抵抗が低いものを用いた場合、電極面において、電源部５１から延出された各配線７１の端子から遠い部分に向かって電圧降下が起きる。このため、電源部５１から所定の電圧を印加しても、電極１１２・１２２における、電源部５１から遠い部分（つまり、各配線７１の端子から遠い部分）には、調光装置４０の駆動に必要な電圧が印加されず、フレークが動作し難くなる。 For example, when a medium having a low electrical resistance is used as the medium 131 in the light modulation layer 130, a voltage drop occurs toward a portion far from the terminal of each wiring 71 extended from the power supply unit 51 on the electrode surface. For this reason, even if a predetermined voltage is applied from the power supply unit 51, the portions of the electrodes 112 and 122 far from the power supply unit 51 (that is, portions far from the terminals of the wires 71) are driven by the light control device 40. The necessary voltage is not applied, and the flakes are difficult to operate.
　そこで、電極１１２・１２２を分割して個々の面積を小さくすることで、電極面内にあるフレーク層全体に、駆動に必要な電圧を印加することができる。 Therefore, by dividing the electrodes 112 and 122 to reduce the individual areas, a voltage necessary for driving can be applied to the entire flake layer in the electrode surface.
　図７の（ａ）・（ｂ）は、光変調層１３０に電圧を印加する電極を分割して形成した例を示す図である。なお、図７の（ａ）・（ｂ）では、一例として、電極１２２を分割した場合を例に挙げて図示している。 7A and 7B are diagrams showing an example in which an electrode for applying a voltage to the light modulation layer 130 is divided and formed. 7A and 7B, as an example, the case where the electrode 122 is divided is shown as an example.
　図７の（ａ）に示すように、基板１２０における電極１２２を、基板面内で複数の電極１２２ａに分割している場合、各電極１２２ａを引き回して電極取出し部１２３に集約してもよい。このとき、各電極１２２ａの引き回し部１２２ｂは、例えばシール材１４２の下（すなわち、シール材１４２に重なる部分）や、シール材１４２よりも外側に配置する等、光変調層１３０が動作する部分から外すことで、不要な電圧降下を回避することができる。 As shown in FIG. 7A, when the electrode 122 on the substrate 120 is divided into a plurality of electrodes 122a within the substrate surface, each electrode 122a may be routed and integrated into the electrode extraction portion 123. At this time, the routing part 122b of each electrode 122a is from a part where the light modulation layer 130 operates, for example, below the sealing material 142 (that is, a part overlapping the sealing material 142) or outside the sealing material 142. By removing, unnecessary voltage drop can be avoided.
　また、図７の（ｂ）に示すように、基板１２０における電極１２２を、基板面内で複数の電極１２２ａに分割している場合、複数に分割した電極１２２ａそれぞれに対して、引き回し部１２２ｂで引き回すことなく、電極取出し部１２３を設け、各電極取出し部１２３に配線７１を直接接続してもよい。 Further, as shown in FIG. 7B, when the electrode 122 on the substrate 120 is divided into a plurality of electrodes 122a within the substrate surface, a lead-out portion 122b is provided for each of the divided electrodes 122a. The electrode extraction part 123 may be provided without being routed, and the wiring 71 may be directly connected to each electrode extraction part 123.
　このように電極１２２を複数の電極１２２ａに分割する場合、該電極１２２に対向する電極１１２は、電極１２２と同様に分割してもよいし、分割していなくてもよい。なお、電極１１２のみを分割してもよいことは、言うまでもない。 In this way, when the electrode 122 is divided into a plurality of electrodes 122a, the electrode 112 facing the electrode 122 may be divided in the same manner as the electrode 122 or may not be divided. Needless to say, only the electrode 112 may be divided.
　＜窓本体＞
　なお、本実施形態では、透光性部材である窓本体が窓ガラス１１である場合を例に挙げて説明した。しかしながら、本実施形態は、これに限定されるものではなく、窓本体として、ガラス部材（ガラス板）からなる窓ガラス１１に代えて、透明樹脂等の透光性樹脂からなる透光性板材等を用いてもよい。 <Window body>
In addition, in this embodiment, the case where the window main body which is a translucent member was the window glass 11 was mentioned as an example, and was demonstrated. However, the present embodiment is not limited to this, and instead of the window glass 11 made of a glass member (glass plate) as a window main body, a translucent plate material made of a translucent resin such as a transparent resin, etc. May be used.

　例えば、形状異方性部材１３２の材料や、基板１１０・１２０の層構成、駆動電圧等を変更することで、調光装置４０の調光状態を、光透過状態とすることもできるし、散乱による光反射状態とすることもできるし、ミラー反射による光反射（鏡面）状態とすることもできるし、光吸収（黒色）状態とすることもできる。 For example, by changing the material of the shape anisotropic member 132, the layer configuration of the substrates 110 and 120, the driving voltage, and the like, the light control state of the light control device 40 can be changed to the light transmission state, or the light scattering state. It is also possible to have a light reflection state due to mirror reflection, a light reflection (mirror surface) state due to mirror reflection, or a light absorption (black) state.
　また、前述したように、調光装置４０は、表示装置であってもよい。 Further, as described above, the light control device 40 may be a display device.
　何れにしても、本実施形態によれば、調光装置４０を駆動する駆動装置５０の少なくとも一部が、調光システムにおける透光性部材を支持する支持体の支持部（組み込み部）とは別に配設されていることで、上記支持体を分解しなくても容易に電池交換や部品交換、修理等を行うことができる調光システムを提供することができる。 In any case, according to the present embodiment, at least a part of the drive device 50 that drives the light control device 40 is a support portion (a built-in portion) of a support member that supports the light-transmissive member in the light control system. By being separately provided, it is possible to provide a light control system that can easily perform battery replacement, component replacement, repair, and the like without disassembling the support.
　また、本実施形態では、調光システムが調光窓であり、光源として外光（自然光）を利用する場合を例に挙げて説明した。しかしながら、調光システムが、ガラス衝立等、屋内で使用される物品である場合、上記調光システムは、光源として、室内灯を使用してもよく、上記調光システムが、光源として人工光源を備えている構成としても構わない。 In the present embodiment, the case where the light control system is a light control window and external light (natural light) is used as a light source has been described as an example. However, when the dimming system is an article used indoors, such as a glass screen, the dimming system may use an indoor light as the light source, and the dimming system uses an artificial light source as the light source. It does not matter as a configuration provided.

It is possible.
　〔実施形態２〕
　本発明の他の実施形態について、主に図８および図９に基づいて説明すれば、以下の通りである。なお、本実施形態では、実施形態１との相違点について説明するものとし、実施形態１で用いた構成要素と同一の機能を有する構成要素には同一の番号を付し、その説明を省略する。 [Embodiment 2]
The following will describe another embodiment of the present invention mainly with reference to FIGS. In the present embodiment, differences from the first embodiment will be described, and components having the same functions as those used in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted. .
　なお、本実施形態でも、本実施形態にかかる調光システムが調光窓である場合を例に挙げて説明するが、本実施形態は、これに限定されるものではない。 In the present embodiment, a case where the light control system according to the present embodiment is a light control window will be described as an example. However, the present embodiment is not limited to this.
　＜調光窓１の概略構成＞
　図８は、本実施形態にかかる調光窓１の要部の概略構成を示す断面図である。また、図９は、本実施形態にかかる調光窓１における窓本体ユニット１０の要部の概略構成を示す断面図である。 <Schematic configuration of the light control window 1>
FIG. 8 is a cross-sectional view illustrating a schematic configuration of a main part of the light control window 1 according to the present embodiment. Moreover, FIG. 9 is sectional drawing which shows schematic structure of the principal part of the window main body unit 10 in the light control window 1 concerning this embodiment.
　本実施形態にかかる調光窓１は、以下に示す点を除けば、実施形態１にかかる調光窓１と同じ構成を有している。 The light control window 1 according to the present embodiment has the same configuration as the light control window 1 according to the first embodiment, except for the following points.
　実施形態１にかかる調光窓１は、透光性部材（窓本体）として、単板ガラス（窓ガラス１１）を備えている。これに対し、本実施形態にかかる調光窓１は、二重窓であり、図８および図９に示すように、窓本体（透光性部材）として、窓ガラス１１・１２からなる複層ガラスを備えている。 The light control window 1 concerning Embodiment 1 is equipped with the single plate glass (window glass 11) as a translucent member (window main body). On the other hand, the light control window 1 concerning this embodiment is a double window, and as shown to FIG. 8 and FIG. 9, as a window main body (translucent member), the multilayer which consists of window glass 11 * 12 Has glass.
　窓ガラス１１・１２は、同じ外形を有している。窓ガラス１１・１２は、窓ガラス１１・１２の板面に垂直な方向から見たときに、調光装置４０を挟んで、窓ガラス１１（第１の透光性部材）の板面に窓ガラス１２（第２の透光性部材）の板面が重畳するように、スペーサ３２を介して互いに離間して対向配置されている。 The window glasses 11 and 12 have the same outer shape. When viewed from a direction perpendicular to the plate surfaces of the window glasses 11 and 12, the window glasses 11 and 12 have a window on the plate surface of the window glass 11 (first translucent member) with the light control device 40 interposed therebetween. The glass 12 (second translucent member) is disposed to face each other with a spacer 32 therebetween so that the plate surfaces of the glass 12 (second translucent member) overlap.
　このため、本実施形態にかかる調光窓１（調光システム）は、窓ガラス１１・１２（窓本体、透光性部材）、框２０（支持体）、グレーチングチャンネル３１、スペーサ３２、調光装置４０、駆動装置５０（図２参照）、および通信装置６１（図２参照）を備えている。 For this reason, the light control window 1 (light control system) concerning this embodiment is the window glass 11 * 12 (window main body, a translucent member), the eaves 20 (support body), the grating channel 31, the spacer 32, and the light control. The apparatus 40, the drive device 50 (refer FIG. 2), and the communication apparatus 61 (refer FIG. 2) are provided.
　なお、窓ガラス１１・１２は、同じ材料で形成されていてもよく、互いに異なる材料で形成されていても構わない。また、窓ガラス１１・１２の厚みは、互いに同じであってもよく、異なっていても構わない。 Note that the window glasses 11 and 12 may be formed of the same material or different materials. Further, the thicknesses of the window glasses 11 and 12 may be the same or different from each other.
　窓ガラス１１は、屋外に面して配置されており、窓ガラス１２は、屋内に面して配置されている。 The window glass 11 is disposed facing the outdoors, and the window glass 12 is disposed facing the indoors.
　本実施形態のように複層ガラスからなる窓本体に対して調光装置４０を設ける場合、２枚の窓ガラス１１・１２の間に調光装置４０を設けることで、調光装置４０の破損を避けることができる。 When the light control device 40 is provided for the window main body made of the multi-layer glass as in the present embodiment, the light control device 40 is broken between the two window glasses 11 and 12 so that the light control device 40 is damaged. Can be avoided.
　なお、本実施形態でも、調光装置４０は、図９に示すように、例えば、糊剤やＵＶ硬化樹脂等の接着剤層７２（貼着層）で窓ガラス１１に貼り付けられていてもよい。 In this embodiment, the light control device 40 may be attached to the window glass 11 with an adhesive layer 72 (adhesion layer) such as a glue or a UV curable resin, as shown in FIG. Good.
　例えば調光装置４０を近赤外線調光部とする場合、調光装置４０を、屋外側の窓ガラス１１に貼り付けることで、太陽からの近赤外光が、窓ガラス１１と窓ガラス１２との間の空間部に到達する前に近赤外光を遮断することができる。したがって、この場合、夏場に高い遮熱効果を得ることができる。 For example, when the light control device 40 is a near-infrared light control unit, the near-infrared light from the sun is transmitted to the window glass 11 and the window glass 12 by attaching the light control device 40 to the window glass 11 on the outdoor side. Near infrared light can be blocked before reaching the space between the two. Therefore, in this case, a high heat shielding effect can be obtained in summer.
　スペーサ３２には、例えば乾燥剤入りのアルミスペーサや樹脂スペーサ等、既存のスペーサを用いることができる。 As the spacer 32, for example, an existing spacer such as an aluminum spacer containing a desiccant or a resin spacer can be used.
　本実施形態では、調光装置４０が屋外側の窓ガラス１１における、窓ガラス１２との対向面に貼り付けられていることで、スペーサ３２は、調光装置４０と窓ガラス１２との間に配置されている。 In the present embodiment, the light control device 40 is attached to the surface of the outdoor window glass 11 facing the window glass 12, so that the spacer 32 is interposed between the light control device 40 and the window glass 12. Has been placed.
　グレーチングチャンネル３１は、調光装置４０が貼り付けられた窓ガラス１１と窓ガラス１２とを挟むように、窓ガラス１１・１２の周囲に巻き付けられている。窓ガラス１１・１２および調光装置４０は、図８に示すように、グレーチングチャンネル３１により、框２０の組み込み部２４に設けられた凹部２５内に固定されることで、框２０の枠内に保持されている。 The grating channel 31 is wound around the window glasses 11 and 12 so as to sandwich the window glass 11 and the window glass 12 to which the light control device 40 is attached. As shown in FIG. 8, the window glasses 11, 12 and the light control device 40 are fixed in the recess 25 provided in the built-in portion 24 of the basket 20 by the grating channel 31, so that Is retained.
　窓ガラス１１・１２および調光装置４０は、スペーサ３２およびグレーチングチャンネル３１により一体化されている。本実施形態では、窓本体ユニット１０は、窓ガラス１１・１２、調光装置４０、スペーサ３２、およびグレーチングチャンネル３１を含み、これら窓ガラス１１・１２、調光装置４０、スペーサ３２、およびグレーチングチャンネル３１は、一つの窓本体ユニット１０として、一体的に、框２０に組み付けられている。 The window glasses 11 and 12 and the light control device 40 are integrated by a spacer 32 and a grating channel 31. In the present embodiment, the window body unit 10 includes window glasses 11 and 12, a light control device 40, a spacer 32, and a grating channel 31, and these window glasses 11 and 12, the light control device 40, the spacer 32, and the grating channel. Reference numeral 31 denotes a single window body unit 10 that is integrally assembled to the flange 20.
　このため、図９に示すように、調光装置４０が、実施形態１で示したような、シール材１４２で貼り合わされた一対の基板１１０・１２０を備えている場合、シール材１４２は、グレーチングチャンネル３１およびスペーサ３２と対向する位置に配置されていることが好ましい。これにより、一対の基板１１０・１２０間に、シール材１４２として、例えば、強度が強い樹脂製シール材が存在する部分にグレーチングチャンネル３１およびスペーサ３２の圧力がかかるように調光装置４０を設置することができる。さらに、シール材１４２が外部から見えないことにより、意匠性の高い調光窓１を形成することができる。 For this reason, as shown in FIG. 9, when the light control device 40 includes a pair of substrates 110 and 120 bonded together with the sealing material 142 as shown in the first embodiment, the sealing material 142 includes the grating. It is preferable that the channel 31 and the spacer 32 be disposed at positions facing each other. Thereby, the light control device 40 is installed between the pair of substrates 110 and 120 so that the pressure of the grating channel 31 and the spacer 32 is applied to a portion where, for example, a strong resin sealing material exists as the sealing material 142. be able to. Furthermore, since the sealing material 142 is not visible from the outside, the light control window 1 with high designability can be formed.
　なお、図示はしないが、調光装置４０は、シール材１４２が、グレーチングチャンネル３１およびスペーサ３２よりも窓本体ユニット１０の内側、すなわち、框２０の枠の内側に、グレーチングチャンネル３１およびスペーサ３２と対向しないように配置されていてもよい。 Although not shown, in the light control device 40, the sealing material 142 has the grating channel 31 and the spacer 32 on the inner side of the window body unit 10 than the grating channel 31 and the spacer 32, that is, inside the frame of the flange 20. You may arrange | position so that it may not oppose.
　これにより、グレーチングチャンネル３１およびスペーサ３２の圧力がかかる部分は、一対の基板１１０・１２０のうち一方の基板のみが形成された構成とするか、もしくは、配線７１または配線用のフレキシブル基板が配置されるように調光装置４０を形成することができる。 Thereby, the part to which the pressure of the grating channel 31 and the spacer 32 is applied is configured such that only one of the pair of substrates 110 and 120 is formed, or the wiring 71 or the wiring flexible substrate is arranged. Thus, the light control device 40 can be formed.
　なお、上述したように窓本体として複層ガラスを用いたことで、本実施形態にかかる調光窓１には、少なくとも例えばガラスのような固体と例えば空気のような気体との界面が４つ形成される。これらの界面においては、界面反射が起こるため、可視光線を含む光の透過率が低くなる。このため、これらの界面には、反射防止膜が形成されていることが好ましい。例えば、図９に示すように、窓ガラス１１に調光装置４０を貼り付ける場合、調光装置４０における窓ガラス１２との対向面に反射防止膜８１を形成することが好ましい。 In addition, by using the multi-layer glass as the window main body as described above, the light control window 1 according to the present embodiment has at least four interfaces between a solid such as glass and a gas such as air. It is formed. At these interfaces, since interface reflection occurs, the transmittance of light including visible light is lowered. For this reason, it is preferable that an antireflection film is formed on these interfaces. For example, as shown in FIG. 9, when the light control device 40 is attached to the window glass 11, it is preferable to form an antireflection film 81 on the surface of the light control device 40 facing the window glass 12.
　なお、勿論、窓ガラス１１・１２における空気との界面の少なくとも１つに反射防止膜８１が設けられていてもよく、上記４つの界面のうち全ての界面に反射防止膜８１が設けられていても構わない。 Of course, the antireflection film 81 may be provided on at least one of the interfaces with the air in the window glasses 11 and 12, and the antireflection film 81 is provided on all of the four interfaces. It doesn't matter.
　上記反射防止膜８１としては、例えば、ＡＲ（Anti Reflective）フィルムやＬＲ（Low Reflective）フィルム、モスアイフィルム等、既存の反射防止膜を用いることができる。 As the antireflection film 81, for example, an existing antireflection film such as an AR (Anti Reflective) film, an LR (Low Reflective) film, or a moth-eye film can be used.
　〔実施形態３〕
　本発明の他の実施形態について、主に図１０に基づいて説明すれば、以下の通りである。なお、本実施形態では、実施形態１、２との相違点について説明するものとし、実施形態１、２で用いた構成要素と同一の機能を有する構成要素には同一の番号を付し、その説明を省略する。 [Embodiment 3]

　調光装置４０は、窓ガラス１１と窓ガラス１２との間に、窓ガラス１１・１２とは離間して設けられている。 The light control device 40 is provided between the window glass 11 and the window glass 12 so as to be separated from the window glasses 11 and 12.
　調光装置４０は、トリプルガラスの中央のガラスの代わりとして、その両側をスペーサ３２・３２で保持する等、接着剤層（粘着層）を使用せずに設置されている。スペーサ３２には、実施形態２同様、既存のスペーサを用いることができる。 The light control device 40 is installed without using an adhesive layer (adhesive layer), for example, by holding the both sides with spacers 32 and 32 instead of the central glass of the triple glass. As the spacer 32, an existing spacer can be used as in the second embodiment.
　本実施形態でも、２枚の窓ガラス１１・１２の間に調光装置４０を設けることで、調光装置４０の破損を避けることができる。 Also in the present embodiment, the light control device 40 can be prevented from being damaged by providing the light control device 40 between the two window glasses 11 and 12.
　本実施形態では、グレーチングチャンネル３１は、調光装置４０が間に配置された窓ガラス１１と窓ガラス１２とを挟むように、窓ガラス１１・１２の周囲に巻き付けられている。 In this embodiment, the grating channel 31 is wound around the window glasses 11 and 12 so as to sandwich the window glass 11 and the window glass 12 between which the light control device 40 is disposed.
　窓ガラス１１・１２および調光装置４０は、スペーサ３２・３２およびグレーチングチャンネル３１により一体化されている。本実施形態では、窓本体ユニット１０は、窓ガラス１１・１２、調光装置４０、スペーサ３２・３２、およびグレーチングチャンネル３１を含み、これら窓ガラス１１・１２、調光装置４０、スペーサ３２・３２、およびグレーチングチャンネル３１は、一つの窓本体ユニット１０として、一体的に、框２０に組み付けられる。 The window glasses 11 and 12 and the light control device 40 are integrated by spacers 32 and 32 and the grating channel 31.

　クレセント錠４を解錠すると、当接部材６によって押されていた接続部２２１は、バネ２２４の付勢が解かれることで、バネ２２４が元に戻る力により後退する。これにより、接続部２１１と接続部２２１とが離間し、接続部２１１と接続部２２１との電気的接続が解除される。 When the crescent lock 4 is unlocked, the connection portion 221 that has been pushed by the abutting member 6 is retracted by the force with which the spring 224 returns to its original state by releasing the bias of the spring 224. Thereby, the connection part 211 and the connection part 221 are separated, and the electrical connection between the connection part 211 and the connection part 221 is released.
　なお、本実施形態では、接続部２１１と接続部２２１とが、上記引き違い窓を閉めたときに互いに重なり合う縦框２３の互いの対向面に設けた場合を例に挙げて説明したが、本実施形態は、これに限定されるものではない。これら接続部２１１・２２１は、上記引き違い窓を閉めたときに互いに重なり合う縦框２３に設けられた、クレセント錠４のクレセント部と受け部とに設けられていてもよい。 In the present embodiment, the connection part 211 and the connection part 221 have been described by taking as an example the case where the connection part 211 and the connection part 221 are provided on the mutually facing surfaces of the vertical shaft 23 that overlap each other when the sliding window is closed. The embodiment is not limited to this. These connecting portions 211 and 221 may be provided on the crescent portion and the receiving portion of the crescent lock 4 provided on the vertical shaft 23 that overlaps each other when the sliding window is closed.
